(Springfield, Tosti, Tate)
Heart in my mouth, pulse in my head
Mercury rising into the red

The smell of your skin can light up all the fires in me

Hungry to touch, I'm eager to please

Out of control and I hand you the keys
Every night I am burning to make love to you


But don't try to tell me you think it's all physical
It goes much deeper than that


You ought to know it's an affair of the heart

[Chorus:]

It's an affair of the heart
It's an affair of the heart
Have a little blind faith, believe

It's an affair of the heart

When we make love, it's a passionate thing

You shudder and shake, sink your teeth in my skin
I almost believe you were made to be played by my hands


And you got the power, it amazes me still
How you play my emotions with consummate skill
I don't have to look any further than into your eyes


So don't try to tell me you think it's just physical
It goes way deeper than that

You better know it's an affair of the heart

[Chorus]


Don't try to tell me you think it's all physical
It goes much deeper than that

You ought to know it's an affair of the heart

[Chorus]


You better know it's an affair of the heart
It's an affair of the heart

You better know it's an affair of the heart

[Chorus]
